Remote code execution via unfiltered SpEL evaluation
Published Aug 6, 2024 · Updated Aug 6, 2024
Expression language injection in DataGear 5.0.0 allows remote authenticated users to execute arbitrary OS commands through the Data Schema Page. ConversionSqlParamValueMapper.evaluateVariableExpression parses a controllable expression and evaluates it as SpEL without filtering. Exploitation requires a table without a primary key, a crafted data-field value, and invocation of the table view operation.
